Consequently, communications have been positioned as strategic sector for overall development. To drive this initiative, the Office of the. PON (Passive Optical Network) is a fiber-based broadband access technology, with core components including OLT, ODN, and ONU. •The most popular system to realize Fiber To The Home (FTTH) in the world. OLT:. This disclosurerelates to the field of optical network technologies, and in particular, to a splitting apparatus, a dual-mode optical network unit (ONU), an optical network system, and a communication method. Splits are most commonly factors of 2, such as 1x2, 1x4, 1x8, 1x16, 1x32.
